I went home. +

I went

I think that "home" and "downtown" might be the only destinations that directly follow the verb "to go" without needing a preposition. Can anyone think of any others?

Let's see:

overseas/abroad (although that's rather directional, not really a destination)

outside/inside (out/in)

back

There sure aren't many!

hmm, I could only find "go astray".
